34 Claims. (Cl. 104-254) Matter enclosed in heavy brackets E] appears in the original patent but forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.

The present invention relates to improvements in bumping posts of the type in which a bumper head, located between the rails, is supported by the road bed by tension and compression means.

The object of the present invention is, in general, to provide an easily constructed and assembled, yet low cost, bumping post adapted particularly for use with heavy rails and one that is applicable without change to rails of various heights.

One of the primary features of the present invention resides in the provision of a new and improved tension unit comprising a single bar. This bar is curved at the top and according to another feature of the invention is provided with a bumper head Comprising a striking plate welded thereto.

A further object of the present invention is to provide a bumping post comprising separable tension and conipression units adapted to be connected together in installation by an interlocking connection.

A further object of the invention is to provide a simple arrangement for interconnecting the tension and compression units to form a complete bumping post assembly as by means of a slot and wedge.

A further object of the present invention is to provide a bumping post wherein the tension bar is connected directly to a cross piece located underneath the rails, whereby the vertical stresses are carried directly to the bases of the rails instead of into a joint and then into a cross piece, as in prior art bumping posts. An advantage of this construction is that bolts utilized to secure the lower end of the tension unit to the track rails are subjected only to horizontal stresses.

A further object of the present invention is to provide simplified anchoring means for the bumping post.

A still further object of the present invention is to provide improved compression and tension track joints.

Other objects and advantages of the present invention will become apparent from the ensuing description, in the course of which reference is had to the accompanying drawings, in which:

Fig. 16 is a cross-sectional View taken along the line 16 16 of Fig. l5.

Referring now to the figures, and particularly to Figs. l to 3, inclusive, it may be seen that the bumping post, indicated generally by reference character 10, comprises a bumper head 12 supported slightly off center With respect to a pair of rails 14 by a pair of compression members 16 diverging outwardly, downwardly and rearwardly from the bumper head and an integral tension member indicated as a whole by reference character 13 and comprising portions 20 and 22 diverging downwardly, outwardly and forwardly from the bumper head. One of the important features of the present invention resides in constructing the tension member from a single piece of metal, as hereinafter described in greater detail.

Another of the important features of the present invention resides in connecting the tension bar directly to a cross piece 24 so that the vertical stresses resulting from the impact of a car against the bumping post are transmitted directly to the bases of the rails instead of into a joint and then to the bases of the rails. The lower cnds of the tension member are also connected to track fixture plates 26 and 28 which are substantially identical, as will appear hereinafter, except for slight changes necessitated by off-center support of the bumper head and which are adapted to be secured to the rail webs, by suitable means such as bolts. The construction is such that the bolts are subject only to horizontal stresses.

According to another feature of the present inven tion, the compression members 16 are secured directly to compression track fixture plate 30 and 32 which are, in turn, secured to a compression cross piece 34.

In order to control the tendency of the track to rise at the point of tension connection to the road bed and to divide the outward sidewise rail spreading thrust on the compression base members, track stitcning structure is built into the track at the bumping post location. This structure consists of the previously mentioned cross pieces 24 and 34 and longitudinal members. In the illustrated embodiment the longitudinal members comprise a pair of intermediate rails 36 located adjacent the track rails 14 and extending a substantial distance along the track. They are secured to the ties by spikes and to the compression eross piece 34 by rail clips 38 of novel con struction and secured to the cross piece in a novel mauner to be described in greater detail hereinafter.

Additional stiifening is provided by anchor bars 40 secured to rail brackets 42, in accordance with another feature of this invention. The bars are spiked to the ties outside the railsv i4 and tl c brackets are secured to the rails by suitable fastening means preferably such thex bolts 44 utilised also to secure the compression and tension track fixtures to the rails.

The compression unit is best illustrated in Figs. 4 and 6 to 9, inclusive, from which it may be seen to comprise a number' ot structural elements secured together. as by welding, to form a single unit. The compression meinbers 16 are relatively heavy structural elements and preferably channels having their open sides Facing each other. The louer ends of the compression members E6 are conigured so as to seat on the upper surfaces of the compression track fixture plates 30 and 32 so that the members may be welded directly to the plates.

The track lixture plates comprise apertured vertically disposed portions 5d whereby they may be red to the webs of the rails 14 by the previously mentioned bolts 44: intermediate inclined portions 5?. overlying the surfaces of the inner inclined upper surfaces of the rail bases; and horizontal portions S4 welded directly to thc cross piece 34. The track 'tture plates are also configured so that they may be readily attached to rails of various shapes. Track fixture plates of the construction described and which are adapted to be welded to cross pieces in the above described manner, are disclosed and claimed 1*.

in my copending application Serial No. 301.717, filed October 18, 103?.

The cross piece 34 is preferably made of angle iron, as best illustrated in Fig. 8, so that the rail base encircling clips 38 may be welded to the front tace of the vertical downwardly extending portion thereof. According to the presm invention the rail clips 38 are of integral construction so that they may be readily welded to the cross piece, and are located between lhc latter and a rail tie, as illustrated in 8. danger of the rail clips being damaged, and furthermore, the clips assist in transmitting forces resulting from the impact of cars on the bumping post to the track bed. The rigidity of the structure is enhanced by providing the track fixture plates with cut-away corners, as indicated by the reference character 56 in Fig. 9. so that the track xture plates may be welded not only to the cross piece, but also to the rail clips.

To facilitate proper location of the tension and compression units with respect to each other as well as the interconnection thereof` to form the bumping post assembly, one of the units is provided with an aperture and the other with a projection adapted to extend into the aperture. in the instant embodiment the end of the compression unit is closed by means ol a plate 60, hereinafter termed a middle plate, that is apertured as indicated by reference character 62 for the reception of a connecting plate 64 (see particularly Figs. 4 and 6) form ing a part of the tension unit. When the tension and compression units are to be interlocked, the two are brought into the positional relationship shown in Fig. 4. so that the connecting plate 64 oi the tension unit may be inserted into the aperture 62 in the compression unit. The plate Gti is welded to the upper end of the compression members, which are cut at an angle such that the plate is disposed at an angle corresponding to the angle of inclination of the tension unit.

The units are securely locked together by means of a wedge 66 adapted to be inserted into an aperture 68, formed in a top gusset plate 70 welded to the upper inner edges of the U-shaped channels from which the compression members 16 are made. and an inclined aperture 71 in the connecting plate 64. The upper end of the wedge is provided with an apertured portion 72 extending substantially at right angles to the main portion thereof for the reception oi suitable securing means. such as the bolt and nut indicated by rciercncc character '74. The top gusset plate is provided wtih a second aperture '76 through which the bolt 74 extends.

To assist in the proper connection of the tension and Consequently, there is little :i

compression units, the lower end of the wedge 66 is formed with an inclined surface 78 for cooperative association with the inclined aperture 71.

The upper end of the compression unit is strengthened by a bottom gusset plate 82 apertured at 84 in alignment with the wedge 66 so that the latter may be driven out to permit the post to be disassembled. The upper end of the compression unit is additionally strengthened by substantially triangular braces 86 welded to the middle plate 6d and the bottom portions of the channel-shaped compression memhers 16, as best illustrated in Figs. 4 and 6.

Further to facilitate proper location of the compression and tension units, as well as to assist in maintaining the two in proper relationship, a somewhat oval-shaped plate 8S is welded to the outer side of the middle plate 60 immediately above the aperture 62 therein. The plate 88 is of a width such that the lower side of the upper end of the tension member 18 rests thereon, as shown in Fig. 4.

The construction of the tension unit is illustrated particularly in Figs. 4. 5, 6 and 10 to 12, inclusive. Of these, Figs. 4 to 6 illustrate especially the construction of the bumper head, and Figs. l() to 12, inclusive, illustrate the construction of the tension track xture plates 26 and the connection of the divergent tension members 20 and 22 (these members, it should be remembered, are portions of the integral element 18) thereto and to the tension cross piece 24.

The bumper head 12 is constructed as a unit with the tension unit. lt comprises a striking plate 9() of rectangular shape and secured to the tension member so that it is disposed substantially vertically when the bumping post is installed on the track, as illustrated best in Figs. 1 and 2. The striking plate is secured to the tension unit primarily by means of a pair of vertically disposed supporting plates 92 and 94. The rear sides of these plates are cut to provide angularly disposed surfaces 96 and 98 to facilitate the welding thereof to the interior and front surfaces 100 and 102 of the tension bar, which is of substantially rectangular cross-section, as illustrated in Figs. 4 to 6. The plates 92 and 94 are substantially the same except for slight differences occasioned by reason of the ofi-center support of the bumper head. The upper end of the bumper head is closed by a substantially horizontally disposed plate 104, and the rear end of the upper portion is closed by a pair of substantially triangular piece 106. The plate 104 and triangular pieces 106 are welded tn the adjacent structures and, consequently, add to the rigidity and strength of the bumper head.

Additional strength is imparted to the bumper head by a pair of vertically disposed, generally triangular supporting plates 198 and 110. These plates also act as supporting means for the connecting plate 64 which, it may be noted from Figs. 4 to 6, is secured thereto at au angle such that the connecting plate is in the plane of f the compression unit when the post is assembled. Further strength is imparted to the bumper head by a pair of `spacing blocks 112 and 114 located between and Welded to the plates 92 and 198 and the plates 94 and 110, respectively. lt should he understood that the various plates and blocks described above are also welded to the striking plate 90, as illustrated in part in Figs. 4 and 6.

The lower ends of the tension members 20 and 22 are connected directly to the tension cross piece 24 so that the vertical stresses resulting from an impact of the car against the bumping post are transmitted directly to the bases of the rails 14. This construction is illustrated particularly in Figs. 10, l1 and 12, to which reference is now had. The portions 20 and 22 of the tension bar 18 extend below the bases of the rails 14, as well as below the track fixture plates 26 and 2S. The track fixture plates 26 and 28, like the compression track fixtures, are provided with aperturcd vertically disposed portions 12) whereby they may be secured to the webs olI the rails 14 by the fastening means 44; intermediate inclined portions 122 overlying the rail bases; and with horizontally disposed portions 124 welded directly to the upper surface of the tension cross piece 24, which preferably takes the form of an angle iron as illustrated best in Fig. 12. The track fixture plates are made relatively long so that the rear portions 126 (see Fig. 1l) rest on a rail tie while the front portions are welded to the cross piece. The central inner portions of the track fixture plates are cut away, as indicated by reference character 128, so that the lower ends of the tension members may extend therethrough below the xture plates. The described construction permits the lower ends of the tension bar to be welded directly to the fixture plates as wcll as to the vertically disposed portion of the cross piece 24. To insure the transmission of the vertical stresses to the base of the rail, the cross piece 24 is made of a length (see Fig. such that the outer ends thereof are located below the bases of the rails 14.

The strength of the tension track joint is further enhanced by utilization of generally triangular' braces 1.3i) welded to the undersides of the lower ends of the portions 2() and 22 of the tension bar, and the upper ends of which are adapted to abut against a rail tie as shown in Fig. l2. Further strength is imparted to the joint by utilization of generally rectangular spacing blocks 132, welded to the lower ends of the tension bar and to the upper adjacent ends of the cross piece 24 and supporting plates 130, and by generally triangular spacing blocks 134 located between and welded to the lower ends of the tension bar and cross piece 24.

The construction of the anchor bars and brackets 42 is best illustrated in Figs. l0 and 11. From these it may be noted that the forward end of the anchor bar is secured to the underside of a horizontal portion 136 of the bracket 42 so that the bar lies on the ties to which .I

it may be secured by spikes, as previously indicated. It is preferred to weld the bars to the horizontal portions, as indicated, but other securing means, such as pins or bolts, may be used to provide greater flexibility between the bars and brackets. The bracket 42 is provided with an inclined intermediate portion 138 and an apertured, vertically disposed portion 140 so cut that the brackets may be secured to the webs of the rails contemporane ously with and in a manner identical with the track fixtures.

A modied form of bumper head, comprising a curved striking plate, is illustrated in Figs. 13 to 16, inclusive. The striking plate, which is indicated by reference character 150, is secured to the tension bar 18 mainly by a pair of generally triangular, substantially vertically disposed plates 152 and 154 welded to the front surface 102 of the bar. The striking plate is further supported by a pair of spaced-apart, generally triangular, and substantially vertically disposed plates 156 and 158 between which the connecting plate 160 is secured. The connecting plate is provided with an aperture 162 corresponding to the aperture 71 of connecting plate 64. The supporting plates 152 and 156 and the plates 154 and 158 are spaced by suitably configured spacing blocks 164 and 166, respectively, which correspond to the spacing blocks 112 and 114 of the previously described embodiment. The top of the bumper head is closed by a at plate 168 and the rear of the bumper head is closed by a pair of generally triangular blocks 170 and 172. The various plates and blocks are secured in place by welding.

From the foregoing it may be seen that the bumping post of the present invention may be fabricated very simply, as by welding, from parts cut by a torch or the like. The bumping post of the invention is not only adapted readily to be fabricated, but it also provides a substantial structure well able to withstand the heavy impacts to which it is subject in use. Furthermore, the bumping post comprises separable tension and compression units which can be handled separately and which can be readily assembled and secured together by the slot and wedge connection with a minimum of difiiculty.
